Heat Pump Payback in Woodbury, NY
Woodbury, NY: the heat pump payback math
Woodbury is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. The heat pump would cost about $249 more a year to run than the furnace it replaces, a premium with no payback. That's Woodbury's own climate and rates talking, not a hedge or a caveat.

Woodbury's weather, in the numbers that matter
Degree days tell the story here: Woodbury racks up 5083 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 869 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 8.6°F, and the coldest daily reading in the 2024 station record was -0.4°F. That puts the seasonal coefficient of performance at 2.91 for the recommended cold-climate unit. Woodbury needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from Stewart International Airport, the closest NOAA station, 11.9 miles out.
Woodbury's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 4,423 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,509 a year. The gas furnace it replaces burns roughly 53 Mcf a year at $17.58 per Mcf here, for a running cost near $1,260 a year including the old AC (electricity here runs 29.22¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $9,237 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Woodbury
For the verdict in Woodbury to flip, electricity would need to drop to about 23.0¢/kWh from 29.22¢, or gas climb past $22.29 per Mcf from $17.58. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Woodbury; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Woodbury, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $2,581 a year, which recovers the extra $10,000 spent going electric in roughly 3.9 years.
How Woodbury compares nationally
Among 3206 cities, Woodbury's winter puts it at rank 612 for severity, while its size puts it at rank 2894 for population, 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Woodbury
Woodbury, New York is home to about 11,523 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system, this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Woodbury, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Every constant behind this page, the 2.91 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Woodbury's 8.6°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
